NEWER, DECIDUOUS TREES AND SHRUBS.

five years planted, fifteen feet high. At Syon House, near 
London, there is a specimen, twelve feet. In this country, as 
yet, it is rarely to be met with in our ornamental places, 
which is the more remarkable as we do not know a shrub 
which should be planted before it. It comes into bloom a 
month or six weeks later than the other horse-chestnuts, and at 
a period, too, when very few shrubs are in flower, and continues 
a long time. Our best plant at Wodenethe — of which Fig. 91 
is a sketch — twelve years old, is sixty feet in circumference 
and about eight feet high, and has, at the time we write, between 
three and four hundred racemes of flowers, the feathery lightness 
of which, and the fine umbrageous character of the leaves ren- 
der it a most striking and attractive object. 
Pavia rubra (Red-flowering), — which is merely mentioned 
by Mr. Downing, and which is now better known, is a shrubby 
tree, seldom exceeding twenty feet, with reddish flowers suffi- 
ciently distinct to make it desirable — though Pavia humilis 
pendula (the Weeping red pavia ), is even more desirable and at- 
tractive. Mr. Loudon considers this one of the most beautiful 
and interesting forms of Pavia , and recommends horse-chestnuts 
of twenty to thirty years’ growth to be grafted all over with it 
at the points of the shoots ; care being taken afterwards, once 
or twice every year, to rub off all the buds from the stock as 
soon as they appear, so that the entire force of the plant may 
be directed to the nourishment of the scions. 
Pavia carnea pubescens (Downy leaf), from the fact of the 
whole plant, including the young wood, being covered with 
pubescence. 
P. purpurea (Purple) ; P. rubra atrosanguinea (Dark red) ; 
and P. carnea superba (Pale red), are all new varieties to be 
obtained in this country, and of greater or less merit. 
Alnus. The Alder. 
The principle additions to this genus, since the previous 
edition of this work, have been A. cor difolia, (Heart-shaped), 
a tree of some magnitude, a native of Calabria, with 
large, deep green, shining leaves, rather broad and deeply
